摘要： A process of applying an adhesive to an elastomer includes the application to the elastomer of a two part adhesive formulation. The adhesive having a Part A including at least a polyol, an adhesion promoter, a chain extender, a catalyst, a water scavenger; and a Part B comprising: polyurethane prepolymer, adhesion promoter and a plasticizer. The two part adhesive formulation is cured to form the adhesive. In contrast to the prior art, no priming or surface activation is required to obtain a high strength bond to the elastomer. The resulting article of an elastomer with the resultant adhesive is sufficiently strong to result in surface peel off of the elastomer. A kit is provided for the repair of an elastomer without resort to priming the elastomer.

摘要： A two-part adhesive formulation is provided that has an adhesive part A and an activator part B. The part A includes a monomer amount of a methacrylate ester monomer, a crosslinker amount of a polyfunctional monomer, an anti-oxidant, a free-radical polymerization inhibitor, and an adhesion promoter system to improve cured adhesive strength to a substrate, an impact modifier and a toughening agent and a free-radical polymerization initiator. The part B includes an impact modifier, butyl rubber, methacrylate ester monomer, and a free-radical polymerization accelerator yet varies in the weight ratio used relative to part A. Each of the part A and the part B have separate storage stability of at least 300 days at 23° C. A process of applying an adhesive to a substrate is provided that includes combining together parts A and B to form an adhesive mixture and applying the mixture to the substrate and allowed to cure.

摘要： An adhesive two-part formulation is provided that includes an amount of free-radical curable monomers, each of said free-radical curable monomers containing at least one acrylate moiety or at least one methacrylate moiety, a Lewis acid, a thermoplastic resin; and a polymeric impact modifier. Also present in the formulation is an amount of an activator of borane-amine complex, a metal accelerator; and a grafted elastomer with a thermoplastic additive. A process of applying the formulation to a substrate includes mixing together the formulation components such that each part has a storage stability at 50° C. for 30 days where the viscosity at 30 days is within 40% of an initial viscosity. The mixture is applied to the substrate and then allowed to cure to achieve an initial strength of at least 1 MPa lap shear strength within 45 minutes.
